Flexor and Extensor Muscles

Topic: Flexor and Extensor Muscles

Question: Which muscles are stronger, flexor or extensor muscles?

Hypothesis: My hypothesis is that the flexor muscle is stronger because you can pull more with your flexor than pushing with your extensor.

Procedure:
  1. Get into groups
  2. Have one person stand up straight with his / her back against a wall.
  3. Have that person hold the weights in his / her dominant hand
  4. In a "curling" motion, have the student raise and lower the weights until his / her arms get tired.
  5. Repeat steps 2-4 for each member of the group.
  6. Record the data for each member of the group.
  7. Have the first person stand as straight as possible near a wall.
  8. Have the student hold the weights with his / her dominant arm bent near the ear.
  9. In a motion that mimics throwing, have the student extend the weights above his / her head until the dominant arm gets tired.
  10. Repeat steps 7-9 for each member of the group.
  11. Record the data for each member of the group.
